Metamaterials 2017Foreword

It is our great pleasure to welcome you at the 11th Edition of the Metamaterials Congress in Marseille, France. This event is co-organised by the Virtual Institute for Artificial Electromagnetic Materials and Metamaterials (METAMORPHOSE VI) and the Institut Fresnel. Last year we celebrated the 10th Anniversary of the Congress in Crete: it was an occasion for celebration but also to make an assessment of the whole Congress series and plan together the route for the future.

The Congress series, initiated by the European Network of Excellence METAMORPHOSE and convened annually by the METAMORPHOSE VI, was originally intended to gather scientists from the engineering and physics communities working on artificial electromagnetic materials and metamaterials. This was also reflected in the sub-title of the Congress: the International Congress on Advanced Electromagnetic Materials in Microwaves and Optics. However, it has become evident that the concept of metamaterials has gained a much broader breadth and the Congress, consequently, has been attracting in recent years more and more researchers working in many fields of science and technology, including material science and electromagnetism, physics of solids and acoustics, nanofabrication and chemistry, thermodynamics and mechanics, nano- and quantum-mechanics, civil engineering and device design. To reflect this multidisciplinary nature, after an interesting discussion with eminent scientists and close friends of our community, we have decided to modify the sub-title of the Congress, which has become International Congress on Engineered Materials Platforms for Novel Wave Phenomena.

The hope is that the Congress will continue for many years to provide a unique forum for presenting the latest results in the dynamic field of metamaterials and their applications in many fields of science and technology. The Congress traditions, established and nurtured by its long history and predecessors, International Conferences on Complex Media and Metamaterials (Bianisotropics) and Rome International Workshops on Metamaterials and Special Materials for Electromagnetic Applications and TLC, will be further advanced in Marseille. A balanced mix of plenary, invited, contributed and poster presentations, all subjected to rigorous peer review, encompasses diverse aspects of the fundamental theory, modelling, design, applications, fabrication, and measurements.

The Congress is traditionally accompanied by the European Doctoral School on Metamaterials. This year school is devoted to modelling of metamaterials: numerical methods and homogenization techniques.

We would like to thank all our sponsors and colleagues who have helped with the Congress organisation and offered their scientific and technical contributions.

The success of the conference series allows METAMORPHOSE VI, a non-for-profit international association, to provide financial support to a number of participants, particularly students, to operate the European Doctoral Program on Metamaterials (EUPROMETA) and to deliver other services to the broad metamaterials community.

Metamaterials 2017Preface

On behalf of the Technical Program Committee, it is my pleasure to present to you the technical program of Metamaterials’2017, the 11th International Congress on Engineered Material Platforms for Novel Wave Phenomena.

Now more than ten years after the first edition of this conference, originally more focused in microwaves and optics, the metamaterial concept has expanded across fields of expertise and continues to reinvent itself as an enabling technology. This is manifest from our really cross-disciplinary scientific program that in this edition covers a myriad of topics as diverse as acoustics, mechanics, civil engineering, maritime engineering, microwaves, photonics, materials science, nanofabrication techniques, and quantum technology.

This year the scientific sessions are organized in four-parallel tracks of oral talks selected from over 350 submitted articles. The program includes (71) invited and (192) contributed oral presentations. In addition, we have an interactive poster session with 84 presentations, which provides the opportunity for more informal discussions and personal exchanges. I offer my sincere gratitude to all the reviewers who worked very hard to provide insightful and constructive reviews in a timely manner.

The congress highlights are evidently the plenary presentations, and we look forward to listening to the inspiring talks of George Eleftheriades, Mathias Fink, Steven Johnson and Vladimir Shalaev.

We also have two exciting and unique events in the scientific program: the “Physical Reviews Journals Symposium” and the “Nature Research Symposium”. These two special sessions are organized by the Editors of the Physical Review journals and by the Editors of the Nature Publishing Group journals, respectively, and promise to draw attention to new developments within and beyond the traditional domain of metamaterials research and discuss the role of metamaterial technology in the “grand challenges” of the 21st century.

In addition, we will host special sessions on commercialization of metamaterials, microwave metamaterials, hydrodynamic metamaterials for maritime engineering, mechanical metamaterials, acoustic metamaterials for noise reduction, and seismic metamaterials.

I am deeply indebted to all the friends and colleagues who helped us to shape the scientific program.

I wish you a wonderful and fruitful stay in Marseille. Enjoy the conference!

Mario Silveirinha, Chair of the Technical Program Committee

Metamaterials 2017Welcome message

Dear Friends and Colleagues,

We are delighted to welcome you in Provence for the 11th edition of The International Congress on Engineered Material Platforms for Novel Wave Phenomena, Metamaterials 2017. The conference takes place in Marseille, capital of Provence, in the South of France. Marseille, or Massalia in ancient greek, was born 2600 years ago of the union of an indigenous princess, Gyptis, with a navigator from Phocaea in Asia Minor, Protis, who was going to create a Greek trading post on the shores of Lacydon, our present Vieux Port. It seems therefore fairly natural to host Metamaterials 2017 in Marseille, after the very successful conference Metamaterials 2016 held in Crete last September. Marseille is a place that not only has a very rich history, but also high quality education and research. Aix-Marseille University (AMU) was founded in 1409 when Louis II of Anjou, Count of Provence, petitioned the Pisan Antipope Alexander V to create the University of Provence, and it currently has 74,000 undergraduate and postgraduate students, 3,000 PhD students and over 8,000 administrative and research and teaching permanent staff, what makes it the largest French University with a total annual budget of 720 million euros. AMU has close collaboration with the French National Centre for Scientific Research (CNRS), which has a total annual budget of 3.3 billion euros and employs 32,000 administrative and research civil servants and the French Atomic Energy and Alternative Energies Commission (CEA). The CEA hosts the ITER project in Provence, for which 35 nations are collaborating to build the world's largest tokamak to prove the feasibility of fusion as a large-scale and carbon-free source of energy. Institut Fresnel (IF), which has ongoing projects on metamaterials with CEA in Paris-Saclay and ITER, is one of the 130 research centers of AMU, and is also operating under authority of CNRS and the Centrale Marseille engineering school. IF was created at the turn of the millennium and it now has 172 members, 83 of whom are permanent administrative, research and teaching staff, 36 are postdocs and 53 PhD students. IF is renowned for its research in metamaterials for control of electromagnetic, hydrodynamic and seismic waves, as well as for research in nanophotonics and optical components, data processing and random waves and advanced and living imaging.

We wish and hope that you will enjoy the conference, you will have the chance to have fruitful discussions with colleagues and friends and to stay updated with the latest important developments in the Metamaterials field not only in electromagnetism, but other wave phenomena.

Moreover, we wish you to enjoy the lectures and the conference time, as well as discover the treasures of Marseille, the National park of Calanques and the Frioul Archipelago and their lovely beaches.

Finally, we would like to acknowledge METAMORPHOSE VI, AMU, CNRS, members of Institut Fresnel and all the conference sponsors and supporters. Their contribution to the organization of the conference is invaluable.

Marseille

Marseille, or Massalia in ancient greek, was born 2600 years ago of the union of an indigenous

princess, Gyptis, with a navigator from Phocaea in Asia Minor, Protis, who was going to create a

Greek trading post on the shores of Lacydon, our present Vieux Port. Through this implantation,

Massalia contributed to the introduction in Gaul of the culture of the vine and the olive tree, money

and writing. It is rapidly emerging as a place of influential exchanges between the Mediterranean

and the Celtic world.

Marseille is now France's largest city on the Mediterranean coast and the largest port for commerce,

freight and cruise ships. The city was European Capital of Culture, 2013. It hosted the European

Wave Control with “Time Materials”

• Mathias Fink, Institut Langevin, ESPCI, CNRS, France

Photonic crystals and Metamaterials are made from assemblies of multiple elements usually arranged in

repeating patterns at scales of the order or smaller than the wavelengths of the phenomena they influence.

Because time and space play a similar role in wave propagation, wave propagation is affected by spatial

modulation or by time modulation of the refractive index. Here we emphasize the role of time modulation.

We show that sudden changes of the medium properties generate instant wave sources that emerge

instantaneously from the entire wavefield and can be used to control wavefield and to revisit the way to

create time-reversed waves. Experimental demonstrations of this approach with water waves will be

presented and the extension of this concept to acoustic and electromagnetic waves will be discussed. More

sophisticated time manipulations can also be studied in order to extend the concept of photonic crystals in

the time domain.

SPECIAL SESSION ON COMMERCIALIZATION OF METAMATERIALS

Organizers: Romain Fleury; Miguel Navarro-Cia; Christos Argyropoulos

Session chairperson: Romain Fleury

MECHANICS I

Session chairperson: Martin van Hecke

Liquid-crystal Based ReconfigurableHolographic Metamaterial Electronically

Scanned Antennas

Invited oral :

• Nathan kundtz, kymetacorp, USA

Electronically scanned antennas have historically suffered from a standard set of challenges: Cost, Power Consumption, Size, and Reliability. Despite massive investments these have never been overcome using a Phased Array Antenna architecture. In order to address these problems, we have developed an electronically scanned antenna which uses a liquid crystal modulated, metamaterials-based, reconfigurable holographic approach to beam steering. This approach allows high performance antennas to be produced using LCD television production methods which, in turn, enable applications for ESAs with several orders of magnitude lower power consumption, weight, and cost. In May Kymeta is releasing its first commercial satellite antenna based on this technology. In this talk I will introduce our design approach including the use of liquid crystals for microwave design, discuss manufacturing methods including considerations of thin-film-transistor technology in ESAs, cover achieved performance levels and technological limits, and discuss applications of broad interest.

Experiments on 3D Micropolar Metamaterials

Invited oral :

• Tobias Frenzel, Institute of Applied Physics and Institute of Nanotechnology, Karlsruhe Institute of Technology (KIT), Germany

• Muamer kadic, Institut FEMTO-ST, CNRS, Université Bourgogne Franche-Comté, France

• Martin Wegener, Institute of Applied Physics and Institute of Nanotechnology, Karlsruhe Institute of Technology (KIT), Germany

We present our work on designing, fabricating, and

characterizing three-dimensional chiral (micropolar)

mechanical metamaterials that exhibit a twist upon

pushing or pulling on them. The twist can exceed

one degree of rotation angle per one percent of axial

strain. Results from experiments, calculations for the

investigated microstructures, and from an effective-

parameter continuum model are in good agreement.

Metamaterials Electronically Scanning Array: Design of Imaging Radars for Autonomous

Vehicles

Invited oral :

• Nathan Landy, Echodyne Corp, USA

• Ioannis Tzanidis, Echodyne Corp, USA

• John Hunt, Echodyne Corp, USA

• Tom Driscoll, Echodyne Corp, Duke University, USA

Radar is an exceptional sensing technology, able to provide direct measurement of bearing (Azimuth and Elevation angle), range and velocity (Doppler) in all weather and all conditions. Contemporary radar offerings are largely bifurcated between high-performance high-cost phased-arrays (such as the Active Electronically Scanned Arrays (AESA) favored by military users) and commercial radars which sacrifice substantial performance in pursuit of lower-costs, often relying on slow and bulky mechanical

Novel Topological Concepts for Reliable Mechanical Wave-guiding

Invited oral :

• Sebastian Huber, ETH Zurich, Switzerland

We discuss novel concepts for reliable mechanical

wave-guiding based an band-topology. Starting from

a formal theoretical framework we demonstrate two

experimental implementation of these new concepts

where we provide evidence for back-scattering

free wave-guides that can be arbitrarily deformed

without any losses in the energy transfer.

NANOANTENNAS

Session chairperson: Mikhail Lapine

Surface plasmons and metasurfaces

Invited oral :

• John Pendry, Imperial College London, United Kingdom

Metallic surfaces support surface plasmon excitations

whose properties are intimately connected to the

surface geometry. For example a flat silver surface

is an excellent mirror, but the same material with a

rough surface is black, reflecting hardly any light.

Here we use transformation optics to relate many

complex surface structures to a single mother

structure. In this way we can classify the spectra of

these complex surfaces. Examples will be given of

singular structures that harvest light, electron energy

loss, van der Waals forces and other properties that

are related to the surface plasmon spectrum.

Mixing colors of light in nonlinear dielectric nanoantennas and metasurfaces

Invited oral :

• Mohsen Rahmani, Australian National University, Australia

• Dragomir Neshev, Australian National University, Australia

Dielectric nanoantennas and metasurfaces are able to

manipulate light wavefronts with highest efficiency,

however their potential for enhancing nonlinear

interactions remains unexplored. Here we show how

ultra-small nanocrystals ordered in a metasurface can

enable enhanced light-matter interaction for efficient

nonlinear wave-mixing. In particular, we show how

designer dielectric metasurfaces can enhance second

and third harmonic generation resulting in complete

nonlinear control of directionality and polarization

state of the harmonics.

High-efficiency surface plasmonmeta-couplers

Invited oral :

• Shulin Sun, Fudan University, China• Qiong He, Fudan University, China

• Shiyi Xiao, Fudan University, China

• Wujiong Sun, Fudan University, China

• JIngwen Duan, Fudan University, China

• Lei Zhou, Fudan University, China

Although surface plasmon polaritons (SPPs) have

found numerous applications in photonics, how to

efficiently excite them remains a grand challenge.

We propose a new mechanism to efficiently couple

SPPs with free-space light based on artificial gradient

metasurfaces. In this talk, we will describe our serial

efforts to realize ultra-thin, flat and subwavelength-

sized meta-couplers to achieve SPP excitations with

very high efficiencies.

Hybrid plasmonic and dielectric nanoantennas: nanoscale hot electron

chemistry, nonlinear optics, and surface-enhanced sensing

Invited oral :

• Stefan Maier, Imperial College London, United Kingdom

We demonstrate how controlled emission of hot

electrons in plasmonic nanoantennas leads to highly

localized nanochemistry. This scheme is utilized

for the assembly of hybrid metallic nanoantennas

consisting both of top-down fabricated elements,

and nanosized colloids. The second part of the

talk will show new results for dielectric and hybrid

metallic/dielectric antennas, based on Si, Ge and

GaP, for highly enhanced harmonic generation and

surface-enhanced sensing.

beam-steering methods. In this talk, we present Echodyne’s Metamaterial Electronically Scanning Array (MESA) platform – a realization of a dynamic metamaterial surface – which enables beam-steering control on-par with phased-arrays but at drastically reduced Cost Size Weight and Power (C-SWaP). As an introduction to Echodyne’s commercialization efforts, we give an overview of the radar market landscape, and look at requirement inputs which drive Echodyne’s R&D and product roadmaps. In particular, we focus on the sizeable opportunity for sensors which address the requirements of autonomous vehicles (self-driving cars, UAV-based delivery services, etc), and the need for high-performance radars which operate in cluttered and non-sparse environments. We present test results from one such example, a MESA radar product designed to enable small, low-flying UAS to perform detection and collision avoidance at long range. We also discuss portions of the design cycle utilized for MESA, and present a semi-analytic technique developed in-house for modeling beam-forming and array-factor in dense arrays. This technique, named Floquet Array Synthesis Tool (FAST), mitigates reliance on time-consumptive full-wave simulation, and empowers fast simulation-fabrication-test design cycles that are invaluable in industry.

Volume Manufacturing and Industrial Applications of Metamaterials:

Rolling Lithography, Holography, Laser Filtering and Photovoltaics

Invited oral :

• Themos kallos, Metamaterial Technologies Inc, Canada

• George Palikaras, Metamaterial Technologies Inc, Canada

In this paper we examine different applications

of metamaterials in industrial environments. We

provide overview of activities in laser filtering and

photovoltaics. We also stress the importance of

manufacturing metamaterials and metasurfaces in

high volume and affordably. Specifically, we focus

on the technique of rolling lithography, which can

produce nanopatterned surfaces over meter-long

lengths.

Active Topological Metamaterials

Invited oral :

• Vincenzo Vitelli, University of Leiden, Physics Department, Netherlands

Liquids composed of self-propelled particles have

been experimentally realized using molecular,

colloidal, or macroscopic constituents. These active

liquids can flow spontaneously even in the absence

of an external drive. Unlike spontaneous active

flow, the propagation of density waves in confined

active liquids is not well explored. Here, we exploit

a mapping between density waves on top of a

chiral flow and electrons in a synthetic gauge field

to lay out design principles for artificial structures

termed topological active metamaterials. We design

metamaterials that break time-reversal symmetry

using lattices composed of annular channels filled

with a spontaneously flowing active liquid. Such

active metamaterials support topologically protected

sound modes that propagate unidirectionally,

without backscattering, along either sample edges

or domain walls and despite overdamped particle

dynamics. Our work illustrates how parity-symmetry

breaking in metamaterial structure combined with

microscopic irreversibility of active matter leads to

novel functionalities that cannot be achieved using

only passive materials.

Wavefront Rerouting with Super-Grating Metasurfaces

• Andrea Alu, The University of Texas at Austin, USA

• Dimitrios Sounas, The University of Texas at Austin, USA

• Younes Radi, The University of Texas at Austin, USA

• Hamidreza Chalabi, The University of Texas at Austin, USA

Gradient metasurfaces have received significant attention

in the past few years, due to their potential for advanced

wave manipulation over a thin surface. Following the first,

largely inefficient proposals to pattern the impinging

wavefront by nanostructuring a plasmonic metasurface,

to date there are several elegant approaches to design

metasurfaces that can imprint a pattern of choice to

the impinging wavefront with large resolution. These

approaches typically consist of discrete implementations

of the continuous surface impedance profile ideally

required to convert a certain wavefront into the desired

one, and they all appear to provide a trade-off between

efficiency and complexity. Here, on the contrary, we

introduce the concept of super-grating metasurfaces,

based on which one can arbitrarily steer an impinging

beam with unitary efficiency by relying on specifically

tailored asymmetric resonances within each unit cell of

a suitably designed periodic grating. Our theory shows

that broadband anomalous reflection and transmission

does not necessarily require the use of continuous

spatial gradients of surface impedance, but they can be

achieved by suitably designed periodic arrays of resonant

particles with specifically tailored asymmetric responses.

In addition to their theoretical importance, these results

can be important for the design of efficient metasurfaces

based on simple and realizable principles.

Enhancing the electrical generation of surface plasmons polaritons with optical

nanoantennas

• Jean-Jacques Greffet, Institut d'optique Graduate School, France

It has been known for a long time that inelastic electron

tunneling can generate light emission. Recently, this

technique has been used to launch surface plasmons

polaritons with a scanning tunneling microscope

tip. Unfortunately, the emission process has a very

low efficiency (lower than one plasmon per 10000

electrons). In this paper, we theoretically show an

enhancement of the surface plasmon excitation

process by more than three orders of magnitude in a

carefully-designed nanopatch antenna. We analyze

the physics of the surface plasmon generation with

a modal formalism. Huge enhancement factors can

be obtained by controlling the coupling between two

different modes of the antenna; one mode with a large

density of states has to be coupled with one mode with

a large radiative efficiency.

Topological Transport Of Rotational Waves In Mechanical Granular Graphene

• Li-Yang Zheng, LAUM, UMR-CNRS 6613, Le Mans France, France

Granular crystals are periodic structures of elastic

beads arranged in crystal lattices. One important

feature of granular crystals is that the interactions

between beads take place via central and non-

central contact forces, leading to the propagation of

rotational and rotational-translational coupled waves

in the crystals. Here, we theoretically demonstrate

that a mechanical granular graphene, a two-

dimensional monolayer honeycomb granular crystal,

with Dirac dispersion can exhibit effective spin-orbit

coupling. Topologically protected one-way transport

of rotational edge waves can be achieved on the

interface of two topological granular graphenes. The

robustness of the edge waves is confirmed by their

spatio-temporal evolution simulations with different

defects.

nanostructure, consisting of a monolayer gold-

nanoparticles and a gold film separated by a TiO2

gap layer (Au-NPs/TiO2/Au-film), is capable of

near-completely absorbing light within the whole

visible region. We demonstrate that the Au-NPs/

TiO2/Au-film device can take advantage of such

strong and broadband light absorption to harvest

hot electrons arising from gap-plasmon decay and

consequently increase the photocurrent generation

and improve the photo-electric-chemical water

being used for a great amount of applications.

In this talk, we will show how the extension of the

spatial periodicity of the materials to include as well

“temporal” periodicity provides phononic crystals

of three additional properties: tunability, gain and

non-reciprocity. These three properties, if properly

combined, can lead to a new set of smart materials

exhibit reflection symmetry only. This is achieved by balancing the influence of the two sub-lattices in the periodic system. Here, this approach is applied to a pair of identical coupled slots, where notches are periodically introduced to the inner and outer conductors in a configuration where each slot individually possesses glide symmetry. As the complete system does not display glide symmetry, the dispersion has the usual pseudo-plasmonic behavior. However, the properties of glide symmetry can be restored by modifying the relative sizes of the notches in the inner and outer conductors, in order to balance their relative effect. The consequence is to vastly reduce the dispersion of the lowest order mode and the reappearance of degeneracies at the Brillouin zone boundary.

Towards low-profile transmitarrays: Multi-objective tradeoffs of inhomogeneous and anisotropic near-field transforming lenses

Invited oral :

• Sawyer D. Campbell, The Pennsylvania State University, USA

• Eric B. Whiting, The Pennsylvania State University, USA

• Daniel Binion, The Pennsylvania State University, USA

• Pingjuan L. Werner, The Pennsylvania State University, USA

• Douglas H. Werner, The Pennsylvania State University, USA

Transmitarray antenna performance is limited by the

amplitude and phase uniformity of the illumination

source. Horns are a common feed-source for

transmitarrays, but require large separation distances

in order to provide uniform illumination, thus,

limiting the ability to realize low-profile horn-fed

transmitarray systems. In order to overcome this

challenge, transformation optics inspired lenses can

be introduced to redistribute the horn’s near field and

provide uniform phase and magnitude illumination

on the transmitarray within a compact space.

Optimization-Based Design Of Thermal Metamaterials

• Ignacio Peralta, CIMEC (UNL/CONICET), Argentina

• Víctor Daniel Fachinotti, CIMEC (UNL/CONICET), Argentina

To gain control over the diffusive heat flux in a

given domain, one needs to engineer a thermal

metamaterial with a specific distribution of

the generally anisotropic thermal conductivity

throughout the domain. Until now, the appropriate

conductivity distribution was usually determined

using transformation thermodynamics. By this way,

only a few particular cases of heat flux control in

simple domains having simple boundary conditions

were studied. Thermal metamaterials based on

optimization algorithm provide superior properties

compared to those using the previous methods. As

a more general approach, we propose to define the

heat control problem as an optimization problem

where we minimize the error in guiding the heat

flux in a given way, taking as design variables the

parameters that define the variable microstructure

of the metamaterial. Anisotropic conductivity is

introduced by using a laminate made of layers of

two materials with highly different conductivities,

the thickness of the layers and their orientation

throughout the domain are the current design

variables. We numerically demonstrate the ability

• Filiberto Bilotti, "RomaTre" University , Italy

In this contribution, we present an antenna system

consisting of a circularly polarized antenna connected

to a topologically protected meta-waveguide. The

system can route the received circularly polarized

signals with opposite handedness towards two

different ports. The topologically protected

waveguide acts as an ortho-mode transducer for

circularly-polarized fields of opposite handedness

received by the antenna. It is realized by pulling two

periodic arrays of metallic cylinders with opposite

bi-anisotropy together. Each array emulates the

spin-orbit interaction through bi-anisotropy and

acts as a symmetric protected topological (STP-)

insulator, but at the interface between the two arrays

the structure supports a topologically protected

surface wave, which is guided in a preferred direction

according to the polarization state of the signal.

We present the principle of operation and some

preliminary numerical results of a complete system,

demonstrating the routing property for circularly-

polarized waves.

Higher Symmetries: A new degree of freedom for the design of periodic structures

In this presentation, we will introduce the concept

of higher symmetries, including both glide and

twist symmetries. We will describe the remarkable

properties of higher symmetries, such as their ability

to produce both large bandgaps and low dispersive

media. Higher-symmetry structures provide a

new degree of freedom for the design of periodic

then we integrate this proposed approach with heat

Revealing The Influence Of Non-Locality On Plasmonic Systems

• Armel Pitelet, Université Blaise Pascal, Institut Pascal, France

• Antoine Moreau, Université Blaise Pascal, Institut Pascal, France

• Emmanuel Centeno, Université Blaise Pascal, Institut Pascal, France

The key mechanism of applied plasmonic relies on

plasmonic guided modes, i.e collective oscillations of

the coupled electromagnetic fields and conduction

electrons of conducting materials like Surface

Plasmons (SP). Due to their characteristic high wave

vector, and so small effective wavelength, SP based

modes like gap-plasmons, or thin metallic slab modes

have the ability to confine and slow down light which

give them their utility in sensing, miniaturization,

and enhanced light-matters interactions. This short

effective wavelength also leads plasmonic modes

to be sensitive to the non-local response of metals

arising from interaction between free electrons in the

jellium. While the trend is towards miniaturization

of plasmonic devices, there is actually very few

experiment revealing the sensitivity of SP like modes

to non-locality. We propose here to give an overview

of the structures which should be able to reveal and

study non-locality in an experimental way, and so to

better assess what are the limitations of the widely

spread Drude's model which completly neglect this

effect on the optical response of plasmonic devices.

Strong Coupling Between Surface Plasmon Polaritons and Molecular Vibrations

The confined electromagnetic field near plasmonic

nanostructures boosts the strength of light-matter

interaction. Novel plasmonic nanostructured material

can be utilized for enhanced photon absorption,

emission, and collection [1]. Electronic excitations, but

also phonons or molecular vibrations couple efficiently

to plasmon modes or even hybridize with them. In

this presentation, we first introduce heavily doped

semiconductor oxides as an interesting plasmonic

material [2]. Based on this material platform layered

structures with ‘tailored’ metals and dielectrics can be

fabricated. An example is the realization of hyperbolic

metamaterials operating at near- and midinfrared

frequencies using Ga-doped ZnO and Sn-doped In2O3

as metallic component [3]. The hyperbolic dispersion

manifests by occurrence of negative refraction and

propagation of light with wave vector values exceeding

that of free-space. Control of the doping level allows

for systematic adjustment of the frequency range

with hyperbolic dispersion from the mid-infrared

up to almost one micrometer. When coupling single

photon emitters to hyperbolic metamaterials, ideally

embedded into them, a dramatic enhancement of

spontaneous emission is expected. In a second part,

we report on strong coupling of surface plasmon

polaritons and molecular vibrations [4]. We consider

an organic/inorganic plasmonic hybrid structure

consisting of a ketone-based polymer deposited

on top of a silver layer. Attenuated-total-reflection

spectra of the hybrid reveal an anticrossing in the

dispersion relation in vicinity of the carbonyl stretch

vibration of the polymer with an energy splitting of

upper and lower polariton branch up to 14 meV. The

splitting is found to depend on the molecular layer

thickness and saturates for μm-thick films. This new

hybrid state holds strong potential for application in

chemistry and opto-electronics.

negative refraction with a single negative medium or

topological metamaterial crystals.

We show the existence of an inherent handedness

(spin) of evanescent-electromagnetic-waves

which is fundamentally locked to the direction

of propagation (momentum). It is universal and

accompanies evanescent waves in total internal

reflection, waveguides/fibers and surface-states.

We will also discuss the concept of Chern numbers

for homogeneous media and how it cannot explain

this universal effect as it arises from causality

requirements on evanescent waves.

On the Design of Perfect Acoustic Metasurfaces

• Ana Díaz-Rubio, Aalto University, Finland

• Sergei Tretyakov, Aalto University, Finland

In the paradigm of anomalous reflection and

transmission, acoustic metasurfaces based on

a linear phase gradient do not provide perfect

coupling between the incident plane wave and the

desired reflected or transmitted wave. In this paper

we introduce a general approach to the synthesis

of metasurfaces for full control of transmitted

and reflected plane waves and show that ideal

performance can be realized. The analysis reveals the

physical properties of metasurfaces necessary for the

implementation of perfect acoustic metasurfaces.

surface modes are obtained at the boundary between

2D domains of distinct topologies, characterized by

non-zero spin-Chern invariants, where a spin degree

of freedom is induced by relying on six-fold rotational

(C6) crystal symmetry combined with time-reversal

symmetry. Experiments are conducted in the

overcome many challenges typically associated

many intriguing functionalities of metasurfaces have

been demonstrated as “a proof of the principle”,

real practical applications of metasurfaces are

still missing. One of the potential application of

metasurfaces is to magnetic resonance imaging

of the near field it is possible to strongly increase

the scanner sensitivity, signal-to-noise ratio, and

Invited oral :

The use of detuned acoustic resonators (DARs) side-attached to an acoustic waveguide is discussed from the perspective of acoustic metamaterials for the realization of narrow transmission bands with slowdown effects (i.e., the acoustic transparency) and narrow-band absorption by terminated waveguides. Both slow sound propagation in narrow transmission bands and subwavelength-sized narrow-band anechoic waveguide terminations are experimentally demonstrated and adequately described using Helmholtz resonators represented with lamped parameters. The example of efficient suppression of a given acoustic room mode with four Helmholtz resonators is also demonstrated.

Egocentric Physics: It's All About Mie

Invited oral :

• Brian Stout, Université Aix-Marseille, Institut Fresnel, France

• Ross McPhedran, CUDOS, School of Physics, University of Sydney, Australia

We show that the physics of anapole excitations

can be accurately described in terms of a quasi-

normal mode interpretation of standard Mie theory

without recourse to Cartesian coordinate based

`toroidal' currents that have previously been used to

describe this phenomenon. In this purely Mie theory

framework, the anapole behavior arises as a result

of a Fano-type interference effect between different

quasi-normal modes of the scatterer that effectively

eliminate the scattered field in the associated

multipole order.

Combinatorial Design of Mechanical Metamaterials

metamaterials that exhibit spatially textured

functionalities. We discuss the underlying mapping

to spin and combinatorial problems, and show

how combinatorial design opens up a new avenue

towards mechanical metamaterials with unusual

order and machine-like functionalities.

Rayleigh limit of high-index dielectric nanowires

• Ory Schnitzer, Imperial College London, United Kingdom

We develop an asymptotic theory for resonant

scattering from subwavelength high-index dielectric

particles. Starting from Maxwell's equations, we apply

the method of matched asymptotic expansions

between a "near-field" region, scaling with particle

size and the wavelength within the dielectric, and

an "outer" region, scaling with a relatively larger

vacuum wavelength. For cylindrical wires, we find

scalings and elementary asymptotic expressions for

scattering cross-sections, directivity, and near-field

enhancement factors, along with an intuitive physical

picture of the near-, outer- and far-field regions. Our

results elucidate the properties of the subwavelength

Mie resonances supported by high-index dielectric

wires. Whereas scattering cross-sections at different

resonant frequencies are comparable, near-field

amplification varies remarkably between modes.

• Domenico Tallarico, University of Liverpool, United Kingdom

We consider a vibrating triangular mass-truss

resonators are linked by trusses to the triangular lattice

nodal points. We assume that the resonator is tilted

, \emph{i.e.} it is rigidly rotated with respect to the

triangular lattice's unit cell by an angle $\vartheta_0$.

This geometric parameter controls a resonant mode in

the spectrum for elastic Bloch waves and affects the

dispersive properties of the lattice. We provide physical

interpretations of these phenomena and discuss

the dynamic implications on elastic Bloch waves. In

addition, we describe a structured interface containing

tilted resonators which exhibits focussing by negative

refraction, as in a ``flat elastic lens''.

Field Patterns: A New Type Of Wave

Invited oral :

• Ornella Mattei, Department of Mathematics, The University of Utah, USA

• Graeme Milton, Department of Mathematics, The University of Utah

Here we introduce the theory of field patterns,

which are a new type of wave. Field patterns occur

in two-phase space-time microstructures when the

microstructure is in some sense commensurate with

the speed of the waves in each phase. Rather than an

instantaneous disturbance triggering a complicated

cascade of disturbances, the disturbances

concentrate on a particular pattern: this is the field

pattern. Our analysis may also be relevant to the

study of the response of microstructured hyperbolic

materials in the quasistatic regime.

Consider two materials with permittivities/

diffusivities of opposite sign, separated by an

interface with a corner. When solving the classic

(local) models derived from electromagnetics

theory, strong singularities may appear. We study

here a nonlocal model for scalar problems with sign-

changing coefficients. Numerical results indicate that

the nonlocal model has some key advantages.

Pillar-Type Acoustic Metasurface

We theoretically and experimentally investigated

the transmission of an anti-symmetric Lamb wave

through a single or a line of pillars deposited onto a

homogeneous plate when the frequency is tuned to

a resonant frequency of the pillars. We show that for

either a bending (dipolar) mode or a compressional

(monopolar) mode, the resonators emit in the plate a

wave 180° out-of-phase with the exciting Lamb wave,

resulting in dips in the transmission spectrum. When

the bending and compressional resonant frequencies

are superposed, the amplitude of the emitted wave

exceeds that of the incident wave, which opens the

possibility for a new out of phase transmission.

In this contribution, we investigate the effect of an infinitely-extended reactive metasurface on the complex input impedance of an electrically small dipole placed in its close proximity. We consider, as a reference scenario, the variation of the input resistance and reactance of a vertical (V-) and horizontal (H-) electric dipole placed above a perfect electric conductor for different electrical distances. Then, the perfect electric conductor is replaced by an inductive and a capacitive metasurface. The complex input impedance of the electric dipole is affected by the presence of the metasurface differently compared to the reference scenario. Our preliminary results demonstrate that a control of the input resistance can be achieved by tuning the surface impedance of the metasurface.

We propose a platonic crystal flat lens capable of

split ring resonators (SRR) arranged in a hexagonal

lattice with attached extra layers, perforated in a

that the flat lens produces negative refraction of

Locally perturbed waveguides with broken symmetry

can be characterized by quasi-trapped modes

interacting with the incident propagating wave. This

interaction leads to Fano resonances with strong

reflection. We show how to cloak such resonance

scattering in water wave channels using variable

smooth bathymetry.

Optical excitations sustained by atomic-scale

materials provide fantastic opportunities to explore

novel ultrafast and quantum-optical phenomena,

as recently argued in great detail for polaritons in

van der Waals materials [1]. Graphene plasmons

play a special role among these excitations due to

their extraordinay electrical, magnetic, and optical

tunability. In this talk, I will review recent advances

obatined by my group on the design and realistic

description of a new class of random metamaterials

incorporating optical gain and displaying a varied

photonic behavior ranging from stable lasing to

chaotic regimes [2]; a new strategy for molecular

sensing that relies on the strong plasmon-driven

nonlinearity of nanographenes [3]; a unique scenario

in which radiative heat transfer is the fastest cooling

mechanism, even beating relaxation to phonons

[4]; the generation of intense high harmonics

from graphene, assisted by its plasmons [5]; and

the possibility of realizing order-one fast light

modulation in ultrathin metal-graphene films. I will

make emphasis on the potential of these phenomena

for the implementation of quantum-optics devices

in a robust solid-state environment under ambient

Importantly, conventional material models, for example

the permittivity response of a magnetized plasma, are

Analytical Solution for the Magnetic Coupling of Two Coils Immersed in a Conductive

Medium

• Son Chu, University of Oxford, United Kingdom

• Andrea Vallecchi, University of Oxford, United Kingdom

• Christopher John Stevens, University of Oxford, United Kingdom

• Ekaterina Shamonina, University of Oxford, United Kingdom

In the presence of a conductive slab, the mutual

inductance of two coupled coils is no longer a real

number but becomes a complex quantity whose

modulus declines for increasing conductivity and

thickness of the slab. In this work, we investigate

the case when the two coils are entirely embedded

in a conductive medium and derive new analytical

formulae for the magnetic vector potential of a

coil in a conductive space with dielectric gaps. Our

results will have a significant impact on the design

and optimisation of magnetoinductive waveguides

for underground/underwater communications and

embedded biomedical systems.

Drift-induced Spasing in Bilayer Graphene

• Tiago Morgado, Instituto de Telecomunicações and Department of Electrical Engineering, University of Coimbra, Portugal

• Mário Silveirinha, Instituto de Telecomunicações and University of Lisbon, Instituto Superior Técnico, Portugal

We demonstrate that a system formed by two

coupled graphene sheets with a drift current may

enable pumping graphene plasmons, leading to

spasing in the mid-infrared range. This regime

relies on exponentially growing wave instabilities

that are triggered by drifting electrons streaming

through one of the graphene sheets. The nanoscopic

characteristic dimensions, together with the

wideband tunability, make the proposed structure

very attractive to be used as on-chip light source in

nanophotonic circuitry.

Removable Tsunami Wall Composed of Acoustic Eaton Lens Array

• Sang-Hoon kim, Mokpo National Maritime University, Korea (South)

A removable tsunami wall made of expandable

rubber pillars or balloons of acoustic Eaton lenses

is proposed theoretically. The lens creates a stop-

band by the rotating the incoming tsunami wave

and reduce the pressure by canceling each other.

The impedance matching on the border of the lenses

results in little reflection. The diameter of each lens is

larger than the wavelength of the tsunami near the

coast, that is, order of a kilometer. Before a tsunami,

the balloons are buried underground in shallow

water near the coast in folded or rounded form.

Upon sounding of the tsunami alarm, water and air

are pumped into the pillars, which expand and erect

the wall above the sea level within a few hours. After

the tsunami, the water and air are released from the

pillars, which are then buried underground for reuse.

Electricity is used to power the entire process. A

numerical simulation with a linear tsunami model was

carried out.

expressions for the energy supplied to macroscopic

magnetization in diamagnetic and paramagnetic

media.

Tunable metasurfaces, whose functionality can

plasmons supported by the graphene, as a tunable

in closed orbits, rooted in two spatially separated

unidirectional topological channels.

The Method Of Matched Asymptotic Expansions For The Accurate Modelling

Of Sub Wavelength Resonance In Acoustic Metamaterial Applications

Invited oral :

• I. David Abrahams, Isaac Newton Institute, University of Cambridge, United Kingdom

• William Parnell, University of Manchester, United Kingdom

The method of matched asymptotic expansions

(MAE) has been used to great effect in applied

mathematics and particularly in low frequency wave

scattering problems. Due to their complexity, low

frequency acoustic resonance problems are usually

modelled by more simple `equivalent' systems, e.g.\

spring-mass models for the Helmholtz resonator.

Here the method of MAE is employed in order to

accurately model a wide range of scattering problems

where resonance plays a key role. Leading order

results reproduce some classical models and higher

order corrections allow more complex situations to

be analysed and understood. It is anticipated that

such models can be of great utility in the field of

acoustic metamaterials.

Within the range of validity of the stationary diffusion

• Miguel Beruete, Universidad Pública de Navarra, Spain

• Alejandro Martínez, Universitat Politècnica de València, Spain

• Carlos Garcia-Meca, Universitat Politècnica de València, Spain

In this work we design an unidirectional invisibility

cloak for a diffusive-light medium based on

transformation optics, which provides a broadband,

passive and polarization-independent performance

and can conceal macroscopic objects. Unlike

the other cloaking designs based on scattering

cancellation or transformation optics, our design can

work under transient illumination, which is crucial in

many applications, like time-of-flight imaging or high-

speed communication systems. We demonstrate

that this technique can also be applied to achieve a

multidirectional performance with a polygonal cloak.

Moreover, we propose and analyze a simpler design

of unidirectional cloak based on a layered stack of

two isotropic materials. The performance of the

designed cloaks is numerically analyzed in transient

regime and the successful concealment of the object

is confirmed.

Tunable Enhancement of Second-Harmonic Generation in Dual Graphene Optical Gratings

• Jianwei You, University College London, United Kingdom

the SHG intensity can be readily controlled via gate

voltage tuning.

Flat and conformal optics with dielectric metasurfaces

Invited oral :

• Andrei Faraon, California Institute of Technology, USA

Flat optical devices based on lithographically

patterned sub-wavelength dielectric nano-structures

provide precise control over optical wavefronts,

and thus promise to revolutionize the field of free-

space optics. I discuss our work on high contrast

transmitarrays and reflectarrays composed of silicon

nano-posts located on top of low index substrates

like silica glass or transparent polymers. Complete

control of both phase and polarization is achieved

at the level of single nano-post, which enables

control of the optical wavefront with sub-wavelength

spatial resolution. Using this nano-post platform, we

demonstrate lenses, waveplates, polarizers, arbitrary

beam splitters and holograms. Devices that provide

multiple functionalities, like simultaneous polarization

beam splitting and focusing are implemented. By

embedding the metasurfaces in flexible substrates,

conformal optical devices that decouple the

geometrical shape and optical function are shown.

Multiple flat optical elements are integrated in optical

systems such as planar retro-reflectors and Fourier

lens systems with applications in ultracompact

imaging systems. Applications in microscopy and the

prospects for tunable devices are discussed.

Perovskite Nanostructures As Meta-Atoms For Mie Resonances Inducing Nonlinear

Optical Enhancement

• Flavia Timpu, ETH Zürich, Switzerland

• Morgan Trassin, ETH Zürich, Switzerland

• Manfred Fiebig, ETH Zürich, Switzerland

• Rachel Grange, ETH Zürich, Switzerland

We measure the linear and the second harmonic

Titanate (BaTiO3) nanostructures. We demonstrate 3

orders of magnitude enhancement of the SHG signal

from individual chemically synthesized nanoparticles

at the linear Mie resonance compared to an

unpatterned layer of BaTiO3. We propose to improve

the control of the size and shape of the nanoparticles

by using BaTiO3 nanocylinders fabricated by focused

Invisible Random Media And Diffraction Gratings That Don't Diffract

• Christopher king, University of Exeter, United Kingdom

• Simon Horsley, University of Exeter, United Kingdom

• Tom Philbin, University of Exeter, United Kingdom

In this work we discuss ways to mathematically

design lossless linear isotropic graded index

permittivity profiles in one and two dimensions which

suppress scattering. This has some counter-intuitive

implications, such as disordered media exhibiting

perfect transmission, and periodic gratings which

don't diffract.

Perfect Refraction

• Martin McCall, Imperial College London, United Kingdom

• Jonathan Gratus, Lancaster University, UK

• Paul kinsler, Lancaster University, UK

The possibility of perfect refraction at an interface is

demonstrated via transformation optics. Surprisingly,

although all incident angles and polarizations are

refracted without reflection, impedance is not

matched at the boundary. Expressing both the

medium eigen-problem and field continuity at

the interface in terms of the field 2-form and the

constitutive map, we are able to show that only

the transformational approach produces perfect

refraction.

dispersion and spacial dispersion leads to the precise

description of effective-medium parameters of a

phononic crystal made of periodic arrangement of

rigid inclusions embedded in a viscothermal fluid

in high-frequency regime where Bragg scattering

phenomena appear. We discuss the interplay

between micro-geometry, frequency, fluid motions,

and dissipative processes, and its impact on the

emergence of macroscopic temporal and spacial

dispersion effects. In this respect, we compare the

local approach based on a two-scale asymptotic

homogenization method, and a general nonlocal

homogenization scheme.

electromagnetics concepts. The acoustic leaky-wave

antenna is amongst the most investigated. Despite

the unfavourable properties of conventional matter

and structures with respect to sound dispersion and

radiation, interesting engineering processes have

been recently proposed that are likely to allow such

peculiar properties. After presenting the developed

one-dimensional leaky-wave antenna design, this

paper discusses two pioneering applications of the

latter: the Acoustic Dispersive Prism and the Single-

Microphone Direction Finding.

In recent years significant efforts have been made to

design and fabricate functional nanostructures for

biomedical applications and precision medicine. These

research activities unlocked a complete new research

field known as nano-theranostics, clinical diagnostics

and therapies based on nanotechnologies. Optical

sensor technology based on plasmonic metamaterials

offers significant opportunities in the field of clinical

diagnostics, particularly for the detection of lower-

molecular-weight biomolecules in highly diluted

solutions. On the other hand, many research groups

are extensively addressing unmet clinical needs

by functionalizing bizarre nanostructures aimed

to increase their biocompatibility and to provide

them with extraordinary functionalities. Hybrid

nano-carriers, viral cargos, organic and inorganic

vectors among others represent only a fraction of

a large variety of systems proposed to achieve local

drug-delivery, photo-thermal and photodynamic

therapies, high resolution imaging and stimulated

specific immune response to treat and monitor

neurodegenerative diseases and cancers. In

this context, we have developed a miniaturized

plasmonic biosensor platform based on hyperbolic

metamaterials supporting highly confined bulk

plasmon guided modes that outperform current

detection technologies. Upon using a grating

technique to couple the optical radiation, different

extreme sensitivity modes with a maximum of

30,000 nm per refractive index unit (RIU) and a

record figure of merit (FOM) of 590 have been

achieved [1-2]. We will also report research activities

based on bio-inspired approaches that harness

non-toxic viral cargos (plant viruses) functionalized

with plasmonic and excitonic materials for longeve

intracellular imaging and drug delivery [3-4].

to enhance nonlinear processes in the gap. Using

a 3-photon absorption process in quantum dots

selectively placed in the metallic, we show a 167±26

we restrict our attention to the case of an isotropic

second-order nonlinear metasurface. We derive

the reflectionless conditions for such a nonlinear

metasurface, and show that those conditions depend

on the direction of wave propagation, which reveals

the nonreciprocal nature of the structure. Next, we

provide approximate transmitted field expressions

obtained by perturbation theory, and we shall present

FDTD validations at the conference.

We clearly observed a continuous increase of the

Importantly, the resonances remain matched when

Non-Local Metasurfaces for Perfect Control of Reflection and Transmission

• Sergei Tretyakov, Aalto University, Finland

• Ana Díaz-Rubio, Aalto University, Finland

• Viktar Asadchy, Aalto University, Finland

• Do-Hoon kwon, Aalto University and University of Massachusetts Amherst, Finland and USA

Reflected and transmitted waves can be shaped by

controlling the phase of reflection and transmission

coefficients of antenna arrays or thin composite

layers. This is the operational principle of phased array

antennas and reflectarrays, which can be used also

to design reflecting and transmitting metasurfaces.

Recently, it has been recognized that such phase-

gradient reflectors always produce some parasitic

scattering into unwanted directions. In this review

talk we present and discuss our recent results on

non-local (spatially dispersive) gradient metasurfaces

which do not have this drawback and demonstrate

perfect anomalous reflection and transmission of

Plasmonic nanostructures provide pathways for light

to generate hot electrons or manipulate chemical

reactions on the nanoscale. However, when the size

of the nanoparticle becomes smaller and smaller it

is questionable whether a classical theory describes

the microscopic behaviour of the electronic system

adequately. Here, we study the optically generated

many-particle dynamics using the density matrix

formalism providing a quantum picture of the optical

response of a metal nanosphere. The resulting

dielectric susceptibility spectra show discrete

resonances resulting from a collective response

mediated by the Coulomb interaction between the

electrons.

Structure Reconfigurable Metamaterial Plate with MEMS Technique for THz Wave

• Zhengli Han, Riken, Japan

This paper reports a structure reconfigurable

metamaterial plate for terahertz (THz) wave beam

shaping. The metamaterial plate contains an array

of micro split ring resonator that controls the local

properties of THz wave transmission or reflection.

We add MEMS (micro electro mechanical system)

component (movable cantilever) to each resonator to

tune its resonance. Therefore by the reconfiguration

on the resonator array, it enables beam shaping

of THz wave when it propagates through the

metamaterial plate.

Static Non-reciprocity in Mechanical Metamaterials

Quantum optics of zero-index media

• Iñigo Liberal, Public University of Navarre, Spain

• Nader Engheta, University of Pennsylvania, United Stated

During recent years zero-index media have offered

unique tools for the control and manipulation of

and techniques could be transplanted and utilized

in the manipulation of quantized fields. As a

specific example, we demonstrate theoretically

that supercoupling phenomena in a N-port epsilon-

and-mu-near-zero (EMNZ) hub can be utilized in

the generation of subradiant, maximally entangled,

multi-qubit states.

by such superlenses is thoroughly inspected by

applying scanning near-field optical microscopy and

spectroscopy. The work here focuses on the impact

of the dielectric polarization in such ferroelectrics,

that provides superlens tunability via the electric field

control of the local-scale optical anisotropy in these

materials.

Metasurfaces for Field Manipulation and Sensing

Invited oral :

• Vincenzo Galdi, University of Sannio, Department of Engineering, Italy

This paper summarizes some recent results on

the design, fabrication and characterization of

metasurfaces for field manipulation and sensing.

First, we present the integration of a phase-gradient

plasmonic metasurface on the tip of an optical fiber.

As possible application examples, we illustrate the

beam steering and the excitation of surface waves.

This latter can find interesting applications in label-

free optical sensing. Subsequently, we present the

design of coding metasurfaces for diffuse scattering.

More specifically, via a theoretical study of the

relevant scaling-laws, we derive some absolute and

realistic bounds on the scattering-cross-section

reduction, and we introduce a simple, deterministic

sub-optimal design strategy.

• Taylor Boyd, Physics Department Lancaster University and the Cockcroft Institute, United Kingdom

• Paul kinsler, Physics Department Lancaster University and the Cockcroft Institute, United Kingdom

• Rosa Leitizia, Engineering Department Lancaster University and the Cockcroft Institute, United Kingdom

Using a wire medium with dielectric wires of varying

Strong Variations of Microwave Field Inside Opal-Based Artificial Crystals

• Anatoly Rinkevich, Institute of Metal Physics, Russia

• Dmitry Perov, Institute of Metal Physics, Russia

Metamaterials based on opal matrix and containing

magnetic particles are studied both experimentally

and theoretically and their complex refractive

coefficients at frequencies of millimeter waveband

are obtained. A parameter, characterizing the

nonuniformity of electromagnetic fields at different

distances from a magnetic particle, has been

introduced and calculated. It is found that the

nonuniformity drastically varies depending on the

distance from magnetic particle and on external

magnetic field.

Optical Metamaterials Resonances with Large Quality Factor

Invited oral :

• Costas Soukoulis, Iowa State University, USA

Most metamaterials (MMs) to date are made

with metallic constituents, resulting in significant

dissipation loss in the optical domain. Therefore,

we need to find other ways to create high-

quality resonators with less dissipative loss for the

meta-atoms. One innovative approach we plan

is to reduce dissipative losses by making use of

dielectrics rather than metals for building the EM

resonators. This avoids resonant loss in the metals

and we indeed demonstrate electric and magnetic

dielectric metamaterial resonators with very large

quality factors. The resulting structures can be

straightforwardly scaled at optical frequencies to

create low-loss MMs with a wide range of properties.

Broadband Suppression of Backscattering at Optical Frequencies

• Mohamed Ismail Abdelrahman, Karlsruhe Institute of Technology, Germany

• Ivan Fernandez-Corbaton, Karlsruhe Institute of Technology, Germany

• Carsten Rockstuhl, Karlsruhe Institute of Technology, Germany

We present a novel approach to realize a broadband

suppression of backscattering at optical frequencies

where materials are intrinsically nonmagnetic.

Our approach relies on using spheres made of

low permittivity materials. Such spheres exhibit

comparable electric and magnetic responses to

the illumination for a large number of multipole

moments over a broad spectrum of wavelengths,

which in turn is the key to a vanishing backscattering.

Metamaterial-Based Bessel Beam Launcher

• Nikolaos Chiotellis, University of Michigan, USA

• Anthony Grbic, University of Michigan, USA

A coaxially fed device that generates Bessel beams

over a broad bandwidth is presented. The concept of

quasi-conformal transformation optics is employed

to engineer an inhomogeneous, isotropic dielectric

region that bends the waves emitted by an electrically

small monopole into a paraxial Bessel beam. The

axicon angle remains relatively constant over a large

frequency range. As a result, non-diffracting, highly

localized pulses (X waves) can be emitted under a

pulse excitation. The design methodology and the

metamaterial implementation of the launcher are

discussed. The device is currently being fabricated.

minimizing absorption, etc ..., we determine the most

efficient beam for the task. We also obtain the figure

of merit of the optimal beam (e.g. in force per Watt),

which sets an absolute uppper bound.

Does Transformation Optics Work At Interfaces?

• Lieve Lambrechts, Vrije Universiteit Brussel, Belgium

• Vincent Ginis, Vrije Universiteit Brussel, Belgium

• Jan Danckaert, Vrije Universiteit Brussel, Belgium

• Philippe Tassin, Chalmers University, Sweden

In this contribution, we use the geometrical

formalism of transformation optics to investigate

reflective properties of discontinuously transformed

media as a function of the coordinate stretching.

Radiative Pulling Forces Nearby a Slab of Hyperbolic Metamaterial

• Igor Nefedov, Aalto University, Finland

• Alexander Shalin, ``Nanooptomechanics" Laboratory, ITMO University, St. Petersburg, Russia

In this paper we demonstrate that a finite-thickness

slab of a hyperbolic metamaterial (HMM),surrounded

by isotropic medium,can support either forward or

backward waves if the negative component of the

permittivity tensor corresponds to the coordinate

axis, orthogonal to slab interfaces. If the waveguide

dispersion is the negative, the lateral radiative force

outside of HMM is always the pullinfg force, i.e. is

directed toward a source of electromagnetic energy

flow.

greatly expanded the possibilities for controlling

electromagnetic waves and static fields. Here, we

present a novel and broadly applicable way to

increase magnetic coupling between two distant

elements, by using the properties of extreme

anisotropic magnetic metamaterials. Based on

transformation optics, we analytically demonstrate

how the magnetic coupling between emitting and

receiving coils in a general system can be enhanced

by surrounding them with magnetic metamaterials,

exactly as if the distance between them has been

reduced. The validity of the theoretical results is

confirmed by experimentally demonstrating that

using magnetic metamaterials results in a boost

on the efficiency in the wireless transmission of

power between circuits, since this efficiency directly

depends on the magnetic coupling between emitter

and receiver.

- Non-covariance and Unfaithfulness in Projective Spacetime Transformation Optics

• Robert Thompson, Karlsruhe Institute of Technology, Germany

• Mohsen Fathi, Payam Noor University, Iran

Developments in Transformation Optics (TO) have

drawn heavily on ideas from general relativity. This

motivates a line of inquiry that seeks a deeper, more

rigorous understanding of the spacetime covariant

formulation of electrodynamics in media, and

generalized ideas from general relativity that can

further enhance TO. We show that basing TO on the

idea of metric transformations is not covariant and

introduces distortions to the desired behaviour of a

light beam, but that these issues can be resolved by

keeping the metric fixed.

and a planar feeding structure, both of which are patterned on a high-permittivity, electrically thin, GaAs

substrate. The metasurface is etched on the top side of the substrate, while the feeding structure, which is

a wideband, leaky-wave, center-fed open-ended slotline, is printed on the bottom side of the substrate. The

Here, we propose three kinds of color filters based on all-dielectric metasurfaces to control color hue,

saturation and value (HSV) at the visible region, respectively. Designed with principle of magnetic resonances

An open ring resonator (ORR) is applied to a half mode substrate integrated waveguide (HMSIW) for the

loaded HMSIW has the same behavior as a shunt series LC resonant circuit with a 3 dB stop-band bandwidth

lower than 5 % and insertion loss above 15 dB. This ORR cell can be useful for the design of higher-order

band-stop filters and reconfigurable HMSIW band-stop filters by placing a varactor diode connected to the

9 - PT symmetry in a quasi-periodic structure with topological edge modes Poster [Hide abstract]

• Nicolas Rivolta, University of Mons, Belgium• Henri Benisty, Institut d'optique Graduate School, France• Bjorn Maes, University of Mons, Belgium

We report on an investigation of topological features of a 1D photonic crystal within the PT symmetry context.

We use the scattering characteristics to analyze the various properties of this structure. Quasi-periodicity

induces the presence of bandgaps in the spectrum. Topology-dependent interface modes are induced in

such gaps by a specific back-to-back arrangement. The behaviour of these interface modes still displays a

non trivial dependence on the crystal, even in a passive system. On this basis, the addition of gain and loss

generates another layer of complexity, with intriguing mode-merging behaviours, anisotropic transmission

resonances and lasing effects.

The knowledge of how meta-atoms couple to each other can significantly improve the understanding of

their optical response and, in general, of metamaterials made from an assembly of meta-atoms. Here, we

concentrate on identifying the eigenmodes of the transfer matrix of the meta-atom. The coupling between

several meta-atoms can be conveniently investigated using their transfer matrices in coordinate systems local

to each meta-atom. This provides a way to study effects of hybridization beyond the dipole and the quasi-

static approximation for arbitrary meta-atoms. We concentrate here on meta-atoms that can be fabricated by

self-assembly and bottom-up strategies.

In this work, we designed graphene nanoribbons (GNRs) with sinusoidal edges. We compared experimentally

and theoretically the plasmonic properties for this structure to the GNRs with straight edges. Simulation

results show very high enhancement of electric field intensity at the edges of the Shaped GNRs in comparison

with the edges of GNRs. Moreover, we investigated the shift of the wavelength of the plasmonic resonance

for the Shaped-GNRs compared to the straight GNRs with the same period. Plasmonic resonance tuning with

electrical doping is more for Shaped GNRs than the GNRs.

• Illia Fedorin, National Technical University Kharkiv Polytechnic Institute, Ukraine

Electrodynamic properties of a hypercrystal formed by periodically alternating two types of anisotropic

metamaterials is studied for the case, when an external magnetic field is applied parallel to the boundaries

of the layers. An effective medium theory which is suitable for calculation of properties of long-wavelength

electromagnetic modes is applied in order to derive averaged expressions for effective constitutive parameters.

It has been shown that providing a conscious choice of the constitutive parameters and material fractions of

magnetic, semiconductor, and dielectric layers, the system under study shows hypercrystal properties for

both TE and TM waves in the different frequency ranges.

corrugated unit cells is split into two branches. After being split, each spoof SPP waveguide branch is used

to feed a row of circularly metallic patches for radiations. The proposed structure can realize wide-angle

beam scanning from backward direction to forward direction as the frequency changes, breaking the limit of

traditional leaky-wave antennas. It is shown that the scanning angle can reach 93 degrees with an average

gain level of 9.6 dBi.

• Morten Willatzen, DTU Fotonik, Technical University of Denmark, Denmark

• Andrei Lavrinenko, DTU Fotonik, Technical University of Denmark, Denmark

Losses play a crucial role when realistic hyperbolic metamaterials are considered. Importantly, losses lead to a

broadening of beams propagating through a hyperbolic medium. Here we show that a part of the loss-induced

broadening can be attributed to phase accumulation of plane-wave components. This phase accumulation

can be canceled out by utilizing hyperbolic media with a negative permeability.

structures exhibit specific dispersions like zero-curvature flat-bands (referred as ultra-flat bands) and linear

dispersions at the center of the first Brillouin zone (so-called Dirac cones). We investigate the origin of these

particular dispersions using temporal coupled modes theory and RCWA simulations. It turns out that the

We have confirmed the existence of longitudinal modes in a wire medium of high epsilon thin rods. The

dispersion relation of these modes has been found to be plasma-like allowing them to be manipulated by

changing the structural parameters of the wire media. Our research in this area was inspired by the theoretical

work done into metal wire media and became an extension of their analysis to dielectric wire media, which

leads to potential uses in mode profile shaping applications.

Perovskite (CH3NH3PbI3) solar cells are attracting more attention in last decade due to rapid development

in its energy conversion efficiency and material properties. Herein, we investigate possibility of enhancing

the amount of reflected light from the back contact using silver nanostructures deposited on the back

contact. Using the principles of Mie’s theory, we calculate the backscattering cross section for many shapes/

dimensions of silver nanostructures. The simulation results suggest that certain structures could enhance

the backscattering while others will reduce it. Based on the results of this work, we could enhance the light

confinement in the active layer of the solar cell, hence increase the overall efficiency of perovskite solar cells.

A multiband compact band stop frequency selective surface (FSS) is proposed based on modified square

loop structures with parasitic patches which can work at L, C and X bands, simultaneously. A major capacitor

created between loop and parasitic patches as well as parallel inductors and added stubs achieve this multiband

behavior. A triple bands structure is designed and simulated to demonstrate the idea which works at 3GHz,

5.3GHz and 11 GHz independent from the polarization of incident wave. Moreover the proposed structure has

a small size equal to 0.095，0.095，c2 where ，c is the free space wavelength. Flexibility in multiband tuning,

Gain enhancement of a monopole antenna is proposed by adding cylindrical shell shaped dielectric layers

around it as effective medium. By modifying the electrical field phases transmitted through the layers, the

antenna gain can be enhanced. In order to produce the same phased field, the effective dielectric permittivity

of this effective medium in each point is controlled by trimming cylindrical shells of the dielectric. This

effective medium is composed of stacked cylindrical dielectric layers with same relative dielectric permittivity

but different thicknesses. Implementing this method prove more than 80 % gain enhancement in monopole

antenna.

current distribution at the waveguide broad wall to achieve collinear configuration with low side lobe level

and high gain, the other AMC type changes the reflection phase from the back and end walls PEC termination

to compact the antenna structure. The simulation results prove that the proposed idea results in 6 dB SLL

reduction, 1.8 dB gain enhancement and about 15 % compactness compared with conventional Elliot one.

and the proposed Closed ring resonator (CRR) both show near perfect antireflection, and the enhanced

• Eric Akmansoy, Université Paris-Sud - Institut d'Electronique Fondamentale, France

We have tailored the effective refractive index of dielectric metamaterials to design a flat lens operating at

terahertz frequencies. The studied dielectric metamaterials consist of high permittivity resonators, whose first

Mie resonance gives rise to resonant effective permeability. The resonance frequency is fixed by the size of the

resonators. By varying this size, we could adjust the value of the resonance of the effective permittivity and,

thereby, of the effective refractive index. Then, we fitted this one to the profile of refractive index of a graded

index flat lens, of which we show that it focuses an incident plane wave at terahertz frequencies and that the

spot in the focal plane is diffraction-limited. It is less than one and a half wavelength thick, its focal length is

only a few wavelengths

In this paper, a compact rectangular dielectric resonator antenna has been introduced in which notched

chamfered technique with the edge metal plate on one side of DRA is used to enhance the bandwidth. The

probe feeding is used to excite the DRA as it can easily optimize by adjusting probe height and its location.

The proposed antenna has a simulated impedance bandwidth of 81.53% from 3.9 to 9.2 GHz (S11 < -10 dB)

shows wide frequency band and 3dB axial-ratio bandwidth of 13.16 % i.e. from 7.31 to 8.34 GHz. DRA is made

up of dielectric constant 9.2 (Rogers TMM 10) with loss tangent tan ， = 0.0022. The main purpose of this

paper is to reduce the size of DRA without any trade-off with its impedance bandwidth, gain and efficiency.

We review how additive manufacturing (AM) can be deployed for the rapid prototyping of microwave

waveguide componentry and antennas. Additive manufacture using fused deposition modelling of such

objects allows new, novel and complex structures to be fabricated with lower impact on the environment

relative to current manufacturing processes, plus the fast turnaround of design to manufacture and test.

Additionally while the resulting physical antenna properties may not be perfect compared to the design or

what can be machined, their RF/microwave performance can be quite forgiving thereby allowing the antenna

design engineer to fully exploit the rapid prototyping concept.

This contribution is corresponding to the toroidal resonance. Also in this part we will show the numerical

confirmation of the dominant toroidal multipole in a narrow frequency range – around 1 GHz. The experimental

It is shown that the introduction of the effective wave vector beyond longwave approximation is correct and

completely describes the Andeson localization of light. Moreover, we have shown that real and imaginary

Transient optical rotatory power (ORP) is measured to clarify the temporal development of ORP by exciting

d-band electrons to the conduction p-band of Au using a circularly polarized light (CPL) pump beam. Three

distinct transient behaviors of ORP are identified, resulting from different energy relaxation processes of hot

electrons that occur during a period of a few picoseconds after pumping. Nonthermal hot electrons experience

the Lorentz force from an inverse Faraday effect and electron-boundary scattering, yielding a pump beam

CPL helicity-dependent transient ORP. Once hot electrons are in thermal equilibrium with the lattice due to

electron-lattice coupling, electron energy is distributed among the occupied states, as described by Fermi-

Dirac statistics. Moreover, the transient ORP is found to be independent of pump beam CPL helicity, which is

well explained by the selection rule of electron excitation and two-temperature model of the electron cooling

process. Theoretical analysis of the transient ORP in terms of the energy relaxation of thermal hot electrons

in CMM is carried out by introducing a temperature-dependent dielectric function and finite-difference time-

domain simulation. It is found that the magnitude of ORP at an elevated temperature is reduced to less than

that at room temperature, which agrees well with the experimental observation.

In this work we propose and study via numerical simulation a new metamaterialinspired device for MRI. The

proposed device is a one-dimensional periodic structure formed by multiple inductively-coupled split-loop

resonators (SLRs). The whole structure at the resonance of its fundamental eigenmode has a homogeneous

magnetic field in a hollow surrounded by the split-loops. It has been shown that the structure can be used as a

wireless radio-frequency coil for magnetic resonance imaging (MRI) of a human arm located inside the SLRs.

In order to tune the resonance to the operational (Larmor) frequency 63.8 MHz of a 1.5-Tesla scanner, each

SLR was loaded to a structural capacity of printed metal strips.

We report the results of experimental and theoretical study of extinction and photoluminescence spectra

of samples with silicon nanocrystals in the proximity of two types of plasmonic modes supported by gold

grating. We show how the sub-surface silicon nanocrystals couple to the plasmonic modes and which

enhancement factor they have in both cases. Our calculations of transmission and photoluminescent spectra

are in agreement with experimental results.

• Camille Perrot, Laboratoire Modélisation et Simulation Multi Echelle, Université Paris-Est, France

We present an analytical approach to model a metasolid accounting for anisotropic effects and rotational

mode. The metasolid is made of hard inclusions, either cylindrical or spherical, embedded in a stiff matrix

via soft claddings. We show that the material exhibit negative mass densities near the translational-mode

resonances, and negative density of moment of inertia near the rotational resonances. Based on derived

analytical expressions, we demonstrate that the resonances associated with additional modes we take into

account, that is, axial translation for cylinders, and rotations for both cylindrical and spherical systems, can

occur at lower frequencies compared to the previously studied plane-translational modes.

In this paper, we present a ultra-wideband radar absorbing structure operating in 5-50GHz frequency range.

Two layer of Frequency Selective Surfaces (FSS) separated by dielectric spacer and having 160 Ω/sq. and 80

Ω/sq. respectively are printed on flexible PC-sheet with home-made water-based MWCNT-ink. For a thickness

of 5mm a measured reflection coefficient bandwidth below -15dB is achieved over a bandwidth of 31GHz

between 9-40GHz band, and agrees very well with simulation. The higher absorption bandwidth of absorber

at normal incidence is benefitted from the stacked gradient of optimized surface resistance of resistive-

FSS structure separated by below ，o/4 spacer besides the bandwidth of the proposed absorber combines

flexibility and compactness.

The morphological parameters of rectangular grids of plasmonic nanoparticles of isotropic and anisotropic

shapes have been retrieved combining Mueller matrix Ellipsometry and the Reduced Rayleigh Equations. We

have recently demonstrated that the RREs are computationally efficient both in terms of memory usage and

CPU time. Spectroscopic MME with variable angle of incidence and full azimuthal rotation of the sample is a

powerful optical technique to characterize both anisotropic and bi-anisotropic materials, and seems to be well

suited to the characterization of metasurfaces. All surfaces in this work were manufactured using Focused

Ion Beam Milling.

on the mode propagation length and experimentally observe the long-range propagating magnetoplasmons.

The magnetoplasmon propagation length is estimated up to 200 um and resonance quality factor up to 1500.

70 - A Compact Broadband Metasurface Based Directive Slot Antenna for Gain Enhancement in C-band

• Sudhakar Sahu, KIIT University, India

• Bajra Panjar Mishra, KIIT University, India

Abstract – In this communication, a single sided rectangular split ring resonator (RSRR) based metasurface

combined with an edge fed slot antenna is proposed to achieve high dielectric constant (epsilon very large-EVL)

and high gain in a broadband of 4-8 GHz. This single layer metasurface is proposed to design low loss, broadband,

high efficient compact lens antenna. The design shows an enhancement in gain of 6 dB for the lens feed slot

in the frequency range 4.6-7.4 GHz. The permittivity (，), permeability (μ) and refractive index (，) variation for

the proposed design are nearly zero in the frequency range of 4.2-7.8 GHz. The high dielectric property of the

permittivity of the metasurface lens facilitates to design compact broadband lens antenna system. The structure

has been designed, simulated and optimized using Finite Element Method based High Frequency Structure

Simulator(HFSS).This broadband high gain lens antenna is suitable for C-band communication.

In this communication, a hybrid metallic strip split ring resonator (SRR) based periodic metamaterial structure

is reported for design of W-band lens antenna for absorption and detection of electromagnetic radiation from

the plasma. By detecting the intensity of electromagnetic radiation reveal local information in the electron

temperature of the emitting radiation. The metamaterial lens has been designed to operate in W-band (70-

110 GHz). The unit cell of periodic metamaterial structure is chosen in such a way that, it offers low loss

and dispersion, wide band and high gain of the lens structure. The metamaterial structure as lens has been

designed, simulated and optimized by commercially available ANSYS HFSS Software. Here we propose a

composite metamaterial (CMM) as unit cell structure to realize near zero refractive index to design low loss

broadband high gain near zero refractive index metamaterial (NZMTM) lens antenna to increase the focusing

effect. Metamaterial lens aperture size is of 1100μm x 550μm x 250μm.

72 - Probing the dynamics of microwave pulses in 1D disordered waveguides

• David Petiteau, Bar-Ilan University, Israel

• Azriel Genack, Queens College of the City University of New-York, United States of America

• Patrick Sebbah, Bar-Ilan University, Israel

We report simulations of the time evolution of microwave pulses inside an open 1D random waveguide made

of alternating dielectric slabs $A$ or $B$. Randomness is either introduced by randomly juxtaposing slabs $A$ or $B$ in between the alternating slabs or by introducing a random thickness on each layer. Simulations are performed on particular random configuration or on a high number of configurations. Microwave pulses play the role of a probe and allow the study of the dynamics of localized modes and extended modes in random waveguides in terms of dwell time of the energy in the sample. This work highlights the diversity of dynamical phenomena arising in single realizations of random configuration when those phenomena are

hidden by large ensemble averages.

We propose a unified physics of gap-plasmon resonators, by considering the way gap-plasmons can be excited and

reflected in structures similar to patch antennas. This gap-plasmon optics allows to explain many of the features of

gap-plasmon resonators, from their extraordinary efficiency at concentrating light to the way they scatter it - or not.

74 - Towards a new frontier of Computational Plasmonics: the Density Functional Tight Binding (DFTB) Method

• Stefania D'Agostino, Center for Biomolecular Nanotechnologies of IIT@UniLe, Lecce, Italy, Italy

• Fabio Della Sala, Institute for Microelectronics and Microsystems (IMM-CNR), Campus Ecotekne, 73100 Lecce, Italy., Italy

Electrodynamics methods have been proved to be useful and powerful tools to theoretically study localized and delocalized surface plasmons. Anyway the recent progresses achieved in fabrication techniques to control sub-nanomater structures and features has lead to search for more rigorous approaches able to theoretically describe nonlocality or the spill-out of conduction electrons, effects well visible in very narrow junctions or sub-nanometers gaps. The main shortcoming of the classical approaches consists, in fact, in losing the intrinsic atomistic structure of matter and in neglecting the quantum mechanical effects. Standard atomistic ab-initio time dependent density functional theory (TDDFT) seems to be the most suitable approach for a complete quantum mechanical treatment of plasmons but it becomes computationally unaffordable for particles sizes of several hundreds of atoms. Here we alternatively propone the time dependent Density Functional Tight-Binding Method (TDDFTB) as an efficient and reliable method to describe the optical propreties of metallic clusters, molecules and their relative interactions at the atomistic level. We present a new empirical strategy to improve the TDDFTB performances and overcome its limits in reproducing ab-initio TDDFT spectra for tetrahedral closed-shell Agn clusters and report on our best results for handtuned on-site energies. With the proposed parametrization

TDDFTB gives results comparable to the reference ones but within a computational time less than 0.1%.

75 - Broad acoustic bandgap switching in structured plates

• Younes Achaoui, Institut FEMTO-ST, Univ. Bourgogne Franche-Comté, France

We report in this paper a broadband gap switching by harnessing resonance coupling between two perforated plates. We first recall and explain the mechanism of bandgap enlargement, which emanates from destructive interferences in one slotted plate. The trade-off between bandwidth and the shielding efficiency is highlighted.

A particular attention is brought to the designed structured plates placed in cascade for broad bandgaps tunability purposes.

We consider an effect of waveguide mode disappearance in the presence of Ag layer. When the layer thickness exceeds a threshold value, the mode becomes leaky. This leads to 3 orders damping of the mode path length at 1 nm increase in the metal thickness. Such giant sensitivity is useful for sensing (e.g. heavy metal

salt sensors), efficient electro-optical modulation, etc.

• Sohee Jeon, Korea Institute of Machinery & Materials, Korea (South)

• Jae Ryoun Youn, Seoul National University, Korea (South)

• Jun Ho Jeong, Korea Institute of Machinery & Materials, Korea (South)

Recently, a number of significant and important researches have been published regarding plasmonic effect due to its extraordinary optical property. Even with its extraordinary property, commercialization is limited by the high price to fabrication. In this situation, a lot of research groups have been focused on nano patterning process in order to produce nano scale of plasmonic structure with cost effective process. However, it is difficult to achieve required and designed precise nanoscale dimensions for plasmonic behavior. For this reason, currently plasmonic structure has been fabricated by using expensive and time consuming method such as focused ion beam milling. From this point of view, nano transfer process can solve current issues. More importantly, nano transfer process does not require etch step compared with nano imprint lithography process or optical lithography. In this study, we fabricated a reflectance type of plasmonic metasurfaces with various nano scales of hole diameter and period patterns for structural color printing by using one-step nano transfer process.

• Won Seok Chang, Korea Institute of Machinery and Materials, Korea (South)

The light-confinement phenomena on the semiconducting ZnO nanograting structure were directly observed by means of confocal microscopy-based scanning photocurrent microscopy (SPCM), exhibiting a high spatial resolution distinguishing the 200 nm width of the ZnO nanostructure. Through diverse periods of nanograting, in this case 600, 800 and 1000 nm, and various incident light intensity levels, we confirmed the period dependent confined modes and thus established the ratio of the photocurrent change according to the incident intensity. Our study can provide accurate and comprehensive information regarding light

confinement depending on the nanostructured geometry compared to conventional methods.

The tunable plasmonic response of graphene to THz radiation make this material extremely promising

for ultrathin devices with dynamically configurable properties. However, modulations of the Fermi level of

graphene, which can be generated by a rapidly varying external gate voltage, demand a non-electrostatic

treatment. We show how the full electrodynamic response of a periodically patterned graphene layer can be

obtained analytically thanks to transformation optics.

The existence of optimal value of radius of the holes (around 100 nm) is shown for hexagonal and square lattices.

82 - Time reflection and time refraction of graphene plasmons

• Galaad Altares Menendez, University of Mons, Belgium

• Bjorn Maes, University of Mons, Belgium

Changing materials in time gives rise to a special type of reflection and refraction. Here we show that graphene

plasmons propagating along a graphene sheet and crossing a temporal boundary experience reflection and

transmission, resembling Fresnel reflection and transmission taking place at a spatial boundary. The temporal

discontinuity we use is a change of Fermi level in the graphene sheet. The shape of the discontinuity can be tailored

to filter specific frequencies. This phenomenon is fairly general and can be extended to other guided resonances.

• Laura Pulido Mancera, Duke University, United States

• David Smith, Duke University, United States

The Discrete Dipole Approximation (DDA) is a

powerful tool used to model and design metasurface

antennas for numerous applications such as

beamforming arrays, holograms, and flat lenses

among others. In this technique, a metasurface is

described as a collection of dipoles (meta-atoms)

characterized by their polarizability. The utility of

this technique relies on polarizability extraction. In

this presentation, we employ Loves Theorem to

develop a comprehensive procedure for retrieving

the polarizability of complementary metamaterial

elements, when these are embedded in different

structures such as: rectangular waveguide,

planar waveguide, and periodic metascreen. We

demonstrate that the extracted polarizability changes

depending on the surrounding settings, highlighting

the importance of proper characterization of meta-

atoms in different environments.

Mapping Directivity of Coupled Dimers of Meta-Atoms

• Andrea Vallecchi, University of Oxford, United Kingdom

• Lianbo Li, University of Oxford, United Kingdom

• Ekaterina Shamonina, University of Oxford, United Kingdom

Arrays of coupled split ring resonators (SRRs)

capable of carrying slow short-wavelength magneto-

inductive waves have been shown to support the

rapidly varying current distributions required for

superdirectivity. However, the superposition of both

electric and magnetic dipole resonance modes

contributing to radiation of SRRs challenge pure

physical intuition in the selection of the optimal dimer

configuration reaching the maximum theoretical value

of superdirectivity. In this paper a comprehensive

analytical model for characterizing the radiation of

dimers of coupled meta-atoms with only one element

being driven is presented. The model leverage

an equivalent circuit description of the coupled

resonators in combination with standard radiation

formulas. Based on this model, maps of directivity are

produced for any orientations of two co-planar split

rings resonant at about 2 GHz, leading to identifying

the conditions for superdirectivity in terms of

orientation and possibly size of the meta-atoms.

The Surface Admittance Equivalence Principle For Cloaking Probleme

• Giuseppe Labate, Politecnico di Torino, Italy

• Andrea Alù, University of Texas at Austin, USA

• Ladislau Matekovits, Politecnico di Torino, Italy

In this paper, we apply a reformulated version of

the Surface Equivalence Principle, originally defined

for radiating phenomena in terms of tangential

fields, to cloaking problems in terms of admittance

functions at an arbitrary boundary. In order to cloak

a dielectric/metallic object, the tangential fields

ratio (admittance) can be controlled at any arbitrary

attached/detached surface boundary. The dispersive

surface admittance cloak, as originally introduced

for Mantle Cloaking, is computed in a closed-form

solution at any frequency regime (quasi-static and

beyond).

Rapid simulation of lossy resonators via a robust spatial map of Green’s tensor

• Parry Chen, Tel Aviv University, Israel

• David Bergman, Tel Aviv University, Israel

• Yonatan Sivan, Ben Gurion University, Israel

We obtain the spatial variation of Green's tensor

of lossy resonators in both source and detector

positions and orientations without repeated

simulation. We construct a simple yet rigorous

eigenmode expansion of Green's tensor, bypassing all

implementation and interpretation issues associated

with the alternative quasinormal eigenmode

methods. Modes are defined by a linear eigenvalue

problem with permittivity rather than frequency as

the eigenvalue. Our simple general implemention

using default in-built tools on COMSOL enables

simulation of arbitrarily-shaped structures, such as

bow-tie antennas. Few eigenmodes are necessary for

nanostructures, facilitating both analytic calculations

and unified insight into phenomena such as Purcell

enhancement, radiative heat transfer, and van der

Waals forces.

for realizing rapidly varying current distributions

required for superdirectivity. Superdirective end-fire

radiation was confirmed for metamaterial dimers in

the GHz range. In this paper we present a theoretical

show that the conditions of superdirectivity differ

significantly from the case of the GHz elements.

We identify superdirective configurations of

dimers of meta-atoms of various shape, resonant

characteristics and separation. This study paves the

way for further work on superdirective metamaterial

concept allows for the comparison of the efficiency

of the metasurfaces, their sensitivities to fabrication

of the periodic structures. The Green’s functions

component represents reactive near field. The multi-

band solutions of the periodic structure are first

obtained from a surface integral equation solution,

which is converted to a linear eigenvalue problem,

giving multiple band solutions simultaneously. The

Green’s function including the scatterers is further

used to formulate dual surface integral equations to

study wave interactions with finite arrays of periodic

scatterers. The Green’s function of the periodic

scatterers satisfies the boundary conditions on all

the scatterers. Thus, the unknowns are only limited

to the boundaries enclosing the finite periodic array.

This greatly improves the computing efficiency.

This approach of solving problems of finite periodic

structures is distinct from the effective medium

theory where the periodic structure is replaced by a

homogeneous material of the effective permittivity

and permeability. The effective medium theory is only

valid at the long wave limit, while this new approach

provides exact solution at all wavenumbers. The

application of this Green’s function is demonstrated

by calculating the reflections from a half-space of

periodic scatterers.

We demonstrate numerically and experimentally

the feasibility of an ultra-thin invisibility cloak for

low frequency antenna applications. We consider a

monopole antenna mounted on a ground plane and

a metallic obstacle located in its near-field. To restore

the radiation patterns of the antenna perturbed by

an obstacle we propose here an electromagnetic

cloak that consists simply of metallic patches

separated from the obstacle by a dielectric substrate.

We show that the radiation patterns of the monopole

antenna can be restored completely owing resonant

electromagnetic modes localized under the patch.

We design a reflective photonic limiter for the

W-band. The design is based on a resonance cavity

filled with the Mott insulator, VO2. At low intensity,

the layered structure displays strong resonant

transmission via the localized cavity mode. As the

pulse intensity increases, the heat-induced transition

from insulating to metallic phase in VO2 occurs,

suppressing the cavity mode and the resonant

transmission; the entire multilayer turns highly

reflective within the entire photonic band gap.

Metadiffusers: sound diffusers with deep-subwavelength dimensions

• Jean-Philippe Groby, Laboratoire d'Acoustique de l'Université du Maine, UMR CNRS 6613, France

We present deep-subwavelength diffusing

surfaces based on acoustic metamaterials, namely

metadiffusers. Sound diffusers are surfaces whose

acoustic scattering distribution is uniform. Here,

we achieve sound diffusion by using acoustic

metamaterials composed by rigidly backed slotted

panels, each slit being loaded by an array of Helmholtz

resonators. Both, strongly dispersive propagation

and slow sound speed are observed inside the slits,

shifting their quarter wavelength resonances to the

deep-subwavelength regime. Thus, the reflection

coefficient of each slit can be tailored to obtain either

customized reflection phase, moderate or even

perfect absorption. By using a set of different slits with

tuned geometry we designed surfaces with spatially-

dependent reflection coefficients having uniform

magnitude Fourier transforms, presenting good

diffusion performance. First, various sub-wavelength

diffusers based on known number-theoretical

sequences such as quadratic residue or primitive root

sequences are presented. Second, accurate designs

for binary, ternary and index sequence diffusers are

presented making use of perfect acoustic absorption.

Finally, a 3 cm thick metadiffuser (1/46 times smaller

than the wavelength) was designed working

efficiently for frequencies ranging from 250 Hz to 2

kHz, i.e., 3 octaves.

Large Scale Elastic Metamaterials for Earthquake Protection

• Federico Bosia, University of Torino, Italy

• Marco Miniaci, University of Le Havre, France

• Anastasiia krushynska, University of Torino, Italy

• Nicola Pugno, University of Trento, Italy

In this paper, we propose and numerically analyse

3D large-scale elastic metamaterials for the shielding

of seismic waves propagating in dissipative soils.

We perform a detailed investigation of the influence

of geometric and mechanical parameters on the

attenuation potential of feasible phononic crystal

and locally resonant metamaterial configurations

in typical frequency and intensity ranges for

seismic waves. Results obtained by Finite-Element

eigenfrequency analysis are confirmed by dynamic

transient simulations for both surface and guided

seismic waves, making this strategy viable for the

protection of civil structures against seismic risk.

• Olivier Poncelet, Institut de Mécanique et d'Ingénierie, France

The homogenization of acoustic metamaterials in the

dynamic regime takes into account finite values of

both frequency and wavenumber, which leads to a

set of constitutive parameters non-local in space and

time. As a consequence of this dynamic description,

additional constitutive parameters emerge, which

are required for the proper description of acoustic

metamaterials. In this talk we will present two

materials where these additional constitutive

parameters are important: A Willis material and a

weakly dispersive metamaterial. The experimental

characterization of these advanced materials will also

be discussed.

with potential applications in seismic protection. This

application of metamaterials theory generates novel

approaches to reduce the seismic waves effects on

seismic metamaterials: 3D inertial resonators, auxetic

metamaterials and the concept of Metacity.

In this work, we numerically and experimentally

investigate the influence of bioinspired hierarchical

organization and material viscoelasticity on the wave

dispersion diagram in metamaterials with self-similar

structures at various spatial scales. The study reveals

that the hierarchical architecture combined with

viscoelastic material properties provides advantages

for the dynamic performance with respect to

conventional metamaterials.

We describe and apply a powerful inverse-design

method based on topology optimization to design

complex photonic crystals supporting Dirac points

formed out of the accidental degeneracy of modes

used to realize EPs of arbitrary order as well as

complex contours of EPs. We bound the possible

enhancements and spectral modifications in the

spontaneous emission rate of emitters in the vicinity

of EPs in both linear and nonlinear media.

constants. The manifestation of damping effects

using both unit cell approaches is presented and

by a two-dimensional electron gas modulated by an

electrostatic potential with the honeycomb symmetry

and by a static spatially-varying magnetic field. The

relation between the tight-binding parameters and

the actual physical parameters is found. The overall

topological properties of the material are determined

consequences of a quantized Hall conductivity on

the photonic topological properties are discussed.

plus reflection) or screw (translation plus rotation)

of the dispersion diagram improves (i.e. the number

of folding and non-interacting intersecting curves is

reduced). Concerning computational cost reduction,

we recall the choice of the irreducible Brillouin zone

in terms of the unit cell symmetries, and we show

that band-gap characteristics can be obtained from

the irreducible Brillouin zone contour, only when

bisectors or diagonals of the unit cell are mirror axes.

Otherwise, the full irreducible Brillouin zone has to be

considered.

Light interaction and quantum transport in atomic chain chirally coupled to a waveguide

In this work we considered light interaction with two-

The chiral coupling allows achieving asymmetric

interaction between the two-level systems, which

strongly affects the light scattering of a guided

atomic chain. We have also build an analytical model

of unidirectional transport of quantum excitation

and verified it with modelling of atoms coupled

that an acoustical diode can be achieved in an airflow

duct by slowing down the acoustic wave with locally

reacting impedance boundary conditions at the

walls. In the Slow Sound region, the effective sound

velocity can be so low that no wave can propagate

against the flow while the propagation is still possible

in the flow direction. This phenomenon can occurs on

a large frequency range that can be extended to very

low frequencies.

we compare this theory with computational results.

The approach clearly outlines how the diffuse Wood's

anomaly corresponds to a surface mode while the

Including non-local absorption in quantum hydrodynamic theory for nano-plasmonic

systems

• Cristian Ciracì, Istituto Italiano di Tecnologia, Italy

The quantum hydrodynamic theory is a promising

method for describing microscopic details of

macroscopic systems. The hydrodynamic equation is

directly obtained from a single particle Kohn-Sham

equation. This derivation allows to straightforwardly

incorporate in the hydrodynamic equation a

viscoelastic term, so that broadening of collective

excitation can be taken into account, as well as a

correction to the plasmon dispersion. The result is an

accurate and computationally efficient hydrodynamic

description of the free electron gas.

Asymptotic analogies for closely packed photonic and phononic crystals

• Alice Vanel, Imperial College London, United Kingdom

• Ory Schnitzer, Imperial College London, United Kingdom

• Richard Craster, Imperial College London, United Kingdom

Mechanical waves through periodic mass-spring

lattices have long acted to gain intuition about waves

through continua containing periodic inclusions such

as photonic crystals. Our aim here, in the limit of

closely arranged inclusions, is to make the analogy

quantitative. Techniques based upon matched

asymptotic expansions are used to replace the crystal

by an effective mass-spring lattice.

Homogenization of metamaterials beyond a local response

• karim Mnasri, Karlsruhe Institute for Technology, Germany

• Andrii khrabustovskyi, Karlsruhe Institute for Technology, Germany

• Christian Stohrer, Karlsruhe Institute for Technology, Germany

• Michael Plum, Karlsruhe Institute for Technology, Germany

• Carsten Rockstuhl, Karlsruhe Institute for Technology, Germany

The discussion of the properties of metamaterials

on physical grounds and their consideration in

applications resides on the assignment of effective

material parameters. Usually, weak spatial dispersion

(WSD) is considered. The metamaterial is then

homogenized by bi-anisotropic material parameters.

However, this is often insufficient as the metamaterial

is characterized by strong spatial dispersion (SSD).

Here, we outline a general approach to homogenize

metamaterials by considering SSD, i.e. considering

constitutive relations beyond a local response. We

study here predominantly the properties of bulk

metamaterials by exploring their dispersion relation

but also outline at the conference the necessary

interface conditions for these advanced constitutive

relations.

of light-trapping structures (LTSs). Since the idea

of light trapping due to some resonances and the

needed very broad band of this effect contradict one

another, we suggest to develop non-resonant all-

dielectric LTSs.

We showed in a recent work that the optical properties

of self-assembled bulk metamaterials made of

“Raspberry-like” plasmonic nanoclusters are well

described by a magnetic permeability parameter μ

that deviates significantly from 1 in visible light. We

question in this paper the validity of the permeability

parameter from an experimental point of view. We

investigate the effect of spatial dispersion near the

plasmon resonance and we quantify the deviation from

the classical permittivity-permeability approach.

the moving receiving antenna demonstrate that,

by covering the antenna with the Doppler cloak,

the observed Doppler shifted signal is frequency

mixed, moving the band of the propagating signal

For an external observer, therefore, the receiving

The electric and magnetic Purcell factor of a hyperbolic

metamaterial (HMM) is studied numerically and

experimentally from impedance of dipole antennas

at microwave frequencies between 5-15~GHz. The

Purcell factor is different for transverse magnetic

(TM) and transverse electric (TE) polarizations as

measured using electric and magnetic dipoles. The

antenna impedance method is used to numerically

calculate the density of states (DOS) of the

metamaterial and is in good agreement with the DOS

obtained from band-structure calculations. We show

that impedance measurements of dipole antenna can

be developed as a versatile tool to study the Purcell

factor and DOS at microwave frequencies.

We proposed a novel Doppler effect based microwave

frequency mixer which mixes the incident wave

with its Doppler shifted frequency, instead of a local

oscillator. The Doppler shifted frequency originates

from an effective moving reflective surface built

inside the mixer. This kind of mixer can be low-cost

without local oscillators, meanwhile the intermediate

frequency is tunable electronically.

light propagation and open a new paradigm for spin

and orbital momenta related phenomena in optical

• Tiago Morgado, Instituto de Telecomunicações and Department of Electrical Engineering, University of Coimbra, Portugal

• Mário Silveirinha, Instituto de Telecomunicações and University of Lisbon, Instituto Superior Técnico, Portugal

Here we suggest a new approach to trap light in an all-

of a Fano resonance and a nonlinear response

enables storing the electromagnetic radiation within

the open dielectric cavity for a long period of time.

The proposed light trapping mechanism may be an

interesting alternative to conventional electrically-

• Ariel Epstein, Technion - Israel Institute of Technology, Israel

We introduce a novel concept for anomalous

bianisotropic metasurfaces, designed to guide a pair

of SWs on each of their facets. The eigenmode is

thus a quadruple of SWs, exchanging power via the

metasurface while propagating along it. Full-wave

simulations verify that these eigenmodes can be

efficiently excited by a localized source, and the SW

interference allows intricate manipulation of near-

field features, holding potential for wireless power

transfer and biomedical imaging applications.

to increase the absorbance bandwidth compared

to periodic media. Numerical simulations show

this effect at 300 GHz. A preliminary experimental

special attention was paid to the formation of dimer-

and trimer-like clusters whose density dependence

is analyzed via closed-forms by assuming a Poisson

• Tania Puvirajesinghe, Aix-Marseille Université, Institut Paoli Calmettes, CRCM, Cell Polarity, Cell signaling and Cancer, Marseille, F-13009, France

We investigate diffusion of a peptide drug through

Graphene Oxide (GO) membranes that are modeled

as a porous layered laminate constructed from

flakes of GO and other polymer based materials.

Our experiments employ a peptide drug and show

a tunable non-linear dependence of the peptide

concentration upon time. This is confirmed using

numerical simulations with a diffusion equation

accounting for the photothermal degradation of

fluorophores and an effective percolation model.

Applications include sustained drug delivery, which is

In this work we show analytically and numerically

that a mushroom-type high-impedance metasurface

with loaded vias is capable to absorb perfectly

electromagnetic TM-polarized plane waves for two

angles of incidence(for normal incidence and for

oblique incidence with a selected angle). Using the

non-local homogenization model we demonstrated

this effect can be achieved due to the two types

of losses: dielectric losses inthe substrate of the

metasurface and ohmic losses in lumped loads

connecting vias and a ground plane. Moreover, we

have shown that the angle of perfect absorption

under oblique incidence can be tuned by varying the

complex impedance of the loads.

Angled hole-mask colloidal lithography fabricated plasmonic chiral Au nano-hooks for

conformational analysis of proteins

I present a novel fabrication method for chiral

nanoparticles. It uses a hole-mask colloidal lithography

approach combined with angled evaporation to

produce plasmonic Au nano-hooks. Those nano-

hooks express significant circular dichroism (CD)

responses which makes them promising candidates

for plasmonically enhanced protein conformation

analysis.
